-To all whom it may conce/rn:

Be it known that l, ERNEST VON JEINSEN, of Omaha, in the county of Douglas and State of Nebraska, have invented a new and improved Self-lubricating Axle-Box; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in t-he art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing Figure l represents a'transvcrse section of' this invention.

Figure 2 is a longitudinal section of the same.

Similar letters indicate corresponding parts.

This invention relates to an axle-box for locomotives or railroad cars, both shells of which are provided with bearing-strips, of felt, or other absorbent material, ex'- tending throughout their entire length7 the absorbent bearing-strip in the lower shell being in contact with a wick, which is pressed up against it by a spring, and the lower end of which dips into an oil-reservoir formed in Athe bottom part of the axle-box in such a manner that the wick is constantly held in contact with the absorbent bearing-strip, notwithstanding the oscillations or changes in the position of the axle-box, and the journal of the axle is at all times supplied with the requisite amou'nt of lubricating material as long as a sufficient supply is ke )t up in the oil-reservoir,

and, furthermore, by the-L sorbent bearing-strips the lubricatingl material is uniformly distributed over the entire length of the journal. v

In the drawing- 'lhe letter A designates the upper, and the letter B the lower shell of au axle-box.

Each of vthese shells is provided with an absorbent bearing-strip, a or b,of felt, orother suitable material, said bearing-strips being inserted into grooves extending throughout the entire length, or-nearly so, of the shells, as 'shown in g. 2 of the drawing.

From the groove in the lower shell extends `a4 hole,

vupper end of a wick, il, which is attached to a spring,

c, which is countersunk below and serves to admit the e, by which the same is constantly pressed up against the absorbent strip b.

The lower end of said spring is held in position by a guiding-piece, i,placed in the oil-reservoir, and retained in the proper relation to the lower` shell by a spring, g. 4 ,Y

The'botton'l end of the wick dips into a reservoir formedin' the lower part of the axle-box, (not shown in the'drawing,) and as the axle rises and falls, the

spring e extends or contracts without allowing theA wick to get out of. contact with the absorbent strip.

By these means 'a constant supply of oil is transmittedfrom the oil-reservoir to the absorbent strip b,

and by it `transferred to the journal of the axle, and',

as the journal revolves, the oil is carried up to the absorbent strip of the upper shell, and thus, by the two absorbent strips, the journal is uniformly lubricated throughout its entire length as long as a sufiicient supply of oil is maintained in the reservoir.

VVha-t I claim as new, and desire to secure by L etters Patent, is-

1. The shells A -B of an axle-box or lubricator, formed with grooves which receive absorbent strips of materaL-a and'b, when combined and operating in connection with the wick d and spring g, substantially as described.

2. The countersunk hole c in the bottom of the shell B, receiving the endof a wick, d, which is pressed upward against the absorbent material b by the spring e, which is held in position by the guiding-piece f in the oilreservoir, and operating in connection with the spring g,"substantially as described.

This specification signed by me this 15th day of i April, 1870. ERNESTVON J EINSEN. Witnesses:
